FRANK LORENZO DOTY, OF CALLIOPE, IOWA.

ROPE-CLAMP.

SPECIFICATION forming part of Letters Patent No. 756,104, dated March 29, 1904.

Application filed August 17, 1903.

T0 aZZ whom it may concern:

Be it known that I, FRANK LORENZO Down a citizen of the United States, residing at Calliope, in the county of Sioux and State of Iowa, have invented certain new and useful Improvements in Rope-Clamps; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in clamps for ropes, cables, rods, tubes, &c. and its object is to provide a device of this character which will be simple and of comparatively inexpensive construction, durable in use,'and very efficient for the purpose intended.

With this and other objects in view the invention consists of certain novel features of Fig. 2 is a side elevation of the same.

construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings, Figure 1 is a front elevation of my improved rope-ci amp.

ig. 3 is a top plan view. Fig. 4 is a horizontal sectional view taken on the line 4 4 of Fig. 1.

In the embodiment of my invention as illustrated in the drawings, the numeral 1 denotes my clamp or clutch, which consists of a guideframe 2 and a clamping-lever 3, pivoted therein. The said frame 2 may be constructed of sheet metal, as shown, and it is adapted to be secured in a vertical position to a suitable base 4. The said frame comprises a verticallyextending semicylindrical channel 5, adapted to receive the rope, cable, rod, tube, or the like which is to be clamped by the lever 3 and which is passed through annular guide-loops 6 and 7 provided at each end of said channel. Said channel portion 5 of the frame is adapted to seat in a groove 8, formed in the base 4,

and in order to secure said frame upon the base nails, bolts, or other fastening means are passed through apertured ears or lugs 9, provided upon each side of the frame at each end thereof. The lever 3 is pivoted upon a pin Serial No. 169,776. (No model.)

10 between arms 11, which project from the ears 9 upon each side of the channel portion 5. The inner and lower end of the lever 3 is formed with a cam-shaped gripping-jaw 12, which is grooved, as shown at 13, to coact with the channel 5 in the'frame 1 to clamp the rope between them. The outer and upper end 14 of the lever 3 is heavier than the inner end, so that the jaw 12 will be normally held in engagement with the rope; A sliding weight 15 may be adjustably mounted upon the outer end of the lever in order that the gripping action of the jaw 12 may be varied.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of my invention will be readily understood. It will be seen that the device is simple, strong, durable, and very efficient in operation, clamping the rope firmly as soon as the lever is released. By simply raising the outer end of the lever the jaw may be quickly disengaged from the rope.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully'described my invention, what I claim, and desire to secure by Letters Patent, is I In a rope-clamp, the combination .with a guide-frame having a channel portion, guideloops at each end of the same, attaching-ears upon each side of said channel portion and arms projecting from said'ears, of a clampinglever pivoted between said arms and having a grooved cam-shaped clamping-jaw at one end and an adjustable weight upon its opposite end, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

FRANK LORENZO DOTY.
